Recognizing these lights and understanding their meanings is crucial for maintaining the vehicle's health and safety. Below are some of the common warning lights, their symptoms, and what actions to take.

1. Check Engine Light (CEL)

Symbol: Engine outline with a yellow or orange color
Symptoms: Illuminates steadily or blinks
Meaning: Indicates a problem with the engine or emissions control system.
Action:
1. If blinking, stop the vehicle immediately and check for serious issues (like misfires).
2. If steady, check the gas cap for a loose seal.
3. Use an OBD-II scanner to read diagnostic trouble codes (DTCs) for further diagnosis.

2. Oil Pressure Warning Light

Symbol: Oil can with a drop
Symptoms: Light may flash or stay on
Meaning: Indicates low oil pressure, which can lead to engine damage.
Action:
1. Pull over safely and turn off the engine.
2. Check the oil level using the dipstick; add oil if low.
3. If the oil level is adequate, have the oil pump or oil pressure sensor checked by a technician.

3. Battery/Charging System Warning Light

Symbol: Battery outline
Symptoms: Light stays on or flickers
Meaning: Indicates a problem with the vehicle's charging system.
Action:

5. Tire Pressure Monitoring System (TPMS) Light

Symbol: Horseshoe shape with an exclamation mark
Symptoms: Light stays on or blinks
Meaning: Indicates low tire pressure or a malfunction in the TPMS.
